Baby raccoons
Close-up images of adorable raccoon kits, or babies, accompany the basic facts about these familiar mammals. Children will learn about the parts of the body, how babies are raised by their mothers after they are born, and how raccoons survive in forests, wetlands, and even cities.

Susceptibility of Raccoon Dogs for Experimental SARS-CoV-2 Infection
Raccoon dogs might have been intermediate hosts for severe acute respiratory syndrome-associated coronavirus in 2002-2004. We demonstrated susceptibility of raccoon dogs to severe acute respiratory syndrome coronavirus 2 infection and transmission to in-contact animals. Infected animals had no signs of illness. Virus replication and tissue lesions occurred in the nasal conchae.

Molecular characterization of oriental eyeworm (Thelazia callipaeda) detected from raccoon (Procyon lotor) and Japanese raccoon dog (Nyctereutes viverrinus) in Kanto region, Japan
Background
The oriental eyeworm
Thelazia callipaeda
(Spirurida: Thelaziidae) is an emerging parasitic ocular nematode of carnivores and humans. In domestic animals and humans, the infection causes varying degrees of inflammation and lacrimation, and wild carnivores represent an important reservoir. In this study we examined the infection status and molecular characterization of
T. callipaeda
in two urban carnivores, raccoons
Procyon lotor
and wild Japanese raccoon dogs
Nyctereutes viverrinus
, in the Kanto region of Japan.
Methods
From January 2020 to December 2021, 193 carcasses including 178 raccoons and 15 raccoon dogs were examined for the presence of worms in the eye. The worms from infected animals (one worm per host) were morphologically identified as
T. callipaeda.
Worms (1–5 worms per host) were subjected to genetic analysis using mitochondrial cytochrome
c
oxidase subunit I gene sequences.
Results
The prevalence of
T. callipaeda
in raccoons and Japanese raccoon dogs was 20.2% (36/178) and 13.3% (2/15), respectively. The
cox1
sequences from 56 worms from 38 animals revealed three haplotypes (h9, h10, and h12). Analysis of multiple worms for five raccoons showed co-infection of two different haplotypes (h9 and h10) in a single host. Comparing our data with published sequences, three sequences obtained from raccoons and raccoon dogs shared the same haplotypes as those reported in humans, dogs, and cats in Japan.
Conclusions
Our findings show a high prevalence of
T. callipaeda
in raccoons, suggesting that this invasive carnivore species serves as an important natural reservoir of
T. callipaeda
in the Kanto region of Japan, an area with the highest human population of the country.

Baylisascaris procyonis Roundworm in Common Raccoon ( Procyon lotor ), Mexico
We found the zoonotic nematode, Baylisascaris procyonis, in a common raccoon (Procyon lotor) in Mexico. Expansion of raccoons into human-dominated regions might increase the risk of B. procyonis infections in humans. Increased surveillance and healthcare provider awareness of baylisascariasis in Mexico will be needed to prevent those infections in humans.

Invasive raccoon (Procyon lotor) and raccoon dog (Nyctereutes procyonoides) as potential reservoirs of tick-borne pathogens: data review from native and introduced areas
In recent decades, populations of the raccoon (
Procyon lotor
) and the raccoon dog (
Nyctereutes procyonides
) have increased and adapted to peri-urban and urban environments in many parts of the world. Their ability to rapidly colonize new territories, high plasticity and behavioral adaptation has enabled these two species to be considered two of the most successful invasive alien species. One of the major threats arising from continually growing and expanding populations is their relevant role in maintaining and transmitting various vector-borne pathogens among wildlife, domestic animals and humans. According to the WHO, over 17% of infectious diseases are vector-borne diseases, including those transmitted by ticks. Every year tick-borne pathogens (TBPs) create new public health challenges. Some of the emerging diseases, such as Lyme borreliosis, anaplasmosis, ehrlichiosis, babesiosis and rickettsiosis, have been described in recent years as posing important threats to global health. In this review we summarize current molecular and serological data on the occurrence, diversity and prevalence of some of the TBPs, namely
Babesia
,
Theileria
,
Hepatozoon
,
Borrelia
,
Rickettsia
,
Bartonella
,
Anaplasma
and
Ehrlichia
, that have been detected in raccoons and raccoon dogs that inhabit their native habitats and introduced areas. We draw attention to the limited data currently available on these invasive carnivores as potential reservoirs of TBPs in different parts of the world. Simultaneously we indicate the need for more research in order to better understand the epidemiology of these TBPs and to assess the future risk originating from wildlife.

SARS-CoV-2 and West Nile Virus Prevalence Studies in Raccoons and Raccoon Dogs from Germany
Unlike farm animals, wild animals are not subject to continuous health surveillance. Individual projects designed to screen wildlife populations for specific pathogens are, therefore, also of great importance for human health. In this context, the possible formation of a reservoir for highly pathogenic zoonotic pathogens is a focus of research. Two of these pathogens that have received particular attention during the last years are the novel severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), due to its fast global spread and high impact to the human health, and, since its introduction into Germany, the flavivirus West Nile virus (WNV). Especially in combination with invasive vertebrate species (e.g., raccoons (Procyon lotor) and raccoon dogs (Nyctereutes procyonoides) in Germany), risk analysis must be done to enable health authorities to assess the potential for the establishment of new wild life reservoirs for pathogens. Therefore, samples were collected from raccoons and raccoon dogs and analyzed for the presence of SARS-CoV-2 and WNV infections in these populations. Molecular biological and serological data obtained imply that no SARS-CoV-2 nor WNV reservoir has been established in these two wild life species yet. Future investigations need to keep an eye on these invasive carnivore populations, especially since the close contact of these animals to humans, mainly in urban areas, would make animal–human transmission a challenge for human health.
